The be dispensed with when the source of light is 5 light which passes through the illuminated placed opposite those 0 d, when the slides perforations of this plate to a sensitized me would have to be held in different frames, dium indicates a completed image, which is also opposite each; but the present arrangement is preferred in order to facilitate manipulation. Beyond these slides are suitable collectors h, arranged to throw light from a suitable source (here shown as an arc-light) through each slide and its screen or screens.

Within the dark room is a suitable stand 7", which holds the perforated plate 2', a focusing-screen 7c, and a sensitive medium 7'. Adjacent each slide a is one or more screens Z, held in the frame g with the slide, so that light can pass through both. These screens Zare placed in either side of the slide or both when the exigencies of the case so require or demand and are of substantially the same size as the slides and provided with series of spots arranged to indicate a weaving cross ing, stitch, or pattern. Two or more of such screens may be used simultaneously, whose combined result will indicate a different crossing than any of them taken alone, in which case they are disposed on either or both sides of the slide.

Referring to Fig. 2, which represents a suitable slide of a flower design to be woven in three different thread crossings and of which the design or cards are to be made, since the whole design is to contain three weaving-stitches, one in each of the parts indicated in the transparent portions 1, 2, and 3, three such slides (represented in Fig. 2) are made, and all those portions not to contain the same thread-crossing are spotted or cut out by a suitable opaque or mask. Each portion of the object on the slide when combined with its respective screen will modify or change the distribution of light passed through it for the purpose herein mentioned. Thus it will be seen that if a slide such as shown in Fig. 3, in which the portions 1 representing the flower are transparent, be placed in one part of this frame, for example, so that light will pass through it to the reflector e, and that another plate (shown in Fig. at) containing the leaves which will be translucent, as indicated at 2, be placed so that light will strike the mirror j" these two parts will be projected simultaneously upon the sensitive medium j. Now if a suitable screen to indicate a weaving-stitchfor example, a satin-crossingbe placed in front or behind the flowers 1 and another screen arranged to indicate, for instance, taffeta be similarly used in conjunction with the plate represented in Fig. 2 the representation of the portions 1 and 2 on the sensitized medium will thus indicate these respective crossings. Now if the plates be removed and the light out off from, say, the lower one, and the plate (indicated in Fig. 5) in which the stems 8 are translucent be placed in the upper part of frame 9 in Fig. 1, and the screen indicating twill-crossing be placed in front of it, then light be projected through both screen and plate these stems will be indicated on. the sensitive iilm with twill-crossings and the other portions of the medium, which have already been exposed, being unil-- luminated, will. not be affected by the light, as is well known.

For simultaneously projecting three partial images upon the screen an apparatus, such as shown in Figs. 6, 7, and 9, is used, in which is a ground glass or other focusing screen capable of being replaced by the sensitive medium 7'; t, the perforated plate within the dark chamber between the lens and sensitive medium; a, the front wall of the chamber; Z), the objective or lens in an opening in said wall; (I, the combination of mirrors or reflectors, (shown in Fig. 9,) having reflecting-faces e, (Z, and 6, being formed as a regular pyramid, in which the axis of the solid angle is in the line of collimation of the ob jective Z).

In a suitable casing s, which carries the series of reflectors, are lenses arranged to focus light on the reflecting-faces c d cl, and opposite each lens is a mirror or reflector c, f, and f, and opposite this system of mirrors or reflectors is the frame g, carrying the slides a and the screens Z, a slide and a screen opposite each mirror, and opposite these slides suitable sources of light and collectors 7L.

Fig. 10 shows an arrangement of mirrors in which there are four reflecting-faces e, (Z, c, and d, and it suffices to saythat any number of pictures or partial pictures can be combined by arranging a corresponding number of reflectors, placedat an angle to one an other, each reflector to receive light from a slide in the same manner as described in Figs. 1 and 6.

Fig. 8 shows the perforated plate 1', in which the holes in the plate are indicated by 1]..

I have heretofore employed for the production of such diagrams a perforated plate, the perforations in which act as a series of pin-hole cameras, in which certain holes are cut out by means of a cover-plate in order to leave open such holes only as will produce the required thread-crossing, and it is obvious that in order to do this these plates must be substantially as large as the perforated plate i and practically as large as the diagram produced. Now in lieu of employing plates of this size in order to cover up the openings in the perforated plate I use plates or screens provided with black spots, each spot actingwhen projected to cut out the illumination of certain perforations in the plate 6, thereby indicating the required threadcrossing. Said screens are of a size corresponding to the slide a used in the projection. Thus when combined with the slide these screens, which contain the black spot, will cause unilluminated portions in the projected image, which unilluminated portions are arranged to fall on perforations in the screen Z, will not illuminate said perforations, and thus cause no photographic record to be made. Such screens instead of being composed of opaque spots on a glass plate can be made as a grating of lines ruled on such, and when two such gratings are placed at an angle to one another, preferably but not necessarily at right angles to one another, the same result will be attained, such lines of course being of different transluceney.

All the screens Z, Figs. 1 and 7, must of course be accurately adjusted, so that when they are projected on the perforated plate t' and sensitive medium j they will register with the required perforations 11 that are to be covered. However, since all of the threadcrossing portions can be seen simultaneously on the ground-glass screen any defects arising from the bad fastening of these platesin position in the frame 9 can be readily corrected and register obtained. Now it is obvious that these thread-crossing plates Z will have their black spots registering with the openings in the perforated plate 1' only in case of particular enlargement, and this enlargement must always be maintained, while at the same time it is necessary to keep the distance of the perforated plate from the objective b, the distance of the screen or the paper from the perforated plate and the distance of the optical apparatus from the frame 9 constant or fixed.

The entire design shown in Fig. 2 will now be reproduced upon the sensitized medium united, the flowers or blossoms 1 indicated in satin thread-crossings, those of the leaves in tafieta, and the stems in twill. If a diaphragm has been used with square holes in it, then these crossings will be indicated in the customary manner as squares, as each illuminated pin-hole produces an image of the diaphragm-opening. To facilitate the reading of the diaphragm when such is desired for a card-punching machine, these different crossings can easily have a different outlinesuch as triangular, circular, crossshaped, or any other desirable indicationby using such shaped diaphragms at the lens opening.

The avoidance of adjustment very materially simplifies the apparatus; but, however, difierent objects are woven in different sizes. Hence the slides which serve for diagrammaking must be taken of such a size that they will give the required fixed enlargement. Such accurate photography can be produced now with the greatest ease by means of wellknown photographic apparatus. It is also evident that a picture can be divided in as many portions as desired and all the portions simultaneously projected upon the screen with their respective threadcrossing, it simply being necessary to arrange suitable numbers of reflecting-mirrors corresponding to the numbers of portions to be combined, in the manner illustrated in Figs. 1 and 7.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is
